Hi everyone - I got a new 2019 PHEV this year and was really thrilled with it for the first 600 miles. Then check engine light started coming on. Dealer fixed it, it happened again a day or two later and so at their request we left it with the dealer and got a loaner. And there it stayed. I got an escalation case number after two weeks, when it became clear that they were trying everything and unable to replicate the problem or even understand why it had happened. An engineer from CA came to look at the car. I was getting ready to invoke lemon law when I learned that KMA and engineers in CA told the service folks at the dealer that they deemed the Hybrid Power Control Unit electrically faulty on the Hybrid Starter Generator temperature circuit. They ordered and shipped that part -- allegedly it's now fixed; I collected the car today (a few days shy of three months since I dropped it off). I don't know what error code this problem was. Will report back if there is an issue again - I just wanted to register what happened, since it seems that others have also had this check engine light problem?
